Re: [fuse-devel] HSFS - an NFS client via FUSE

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

       Thanks for your advise, hsfs can mount now. Just as you say,
the problem is caused by the nfs server which
does not support nfsacl. I'll try the new code.
Best Wishes,
Zhu Ying
